(Cl. 240-415) This invention relates generally to lamps for desired, while the front face of the rear wall 6 motor vehicles and refers more particularly to has a coating of suitable material forming a re the type designed for use as head lamps, fiector 8: A suitable filament 9 is carried by the In the past it has been customary to use elecrear wall 6 at the center thereof and is provided tric bulbs in open reflector sub-assemblies as the with suitable electrical terminals in for connec-- 5 lighting elements in such lamps. However, at tion with electric conductors (not shown). the present time filaments instead of bulbs are The mounting D for the units preferably combeing used in hermetically-sealed units which prises a pair of cooperating frames H and I! include the reflector and lens. In some instances and suitable adjusting screws l3, ll and 15, re-

,0 it is desirable to have a plurality of such units l ect vely. Preferably the outer frame ll car- 10 within a single lamp casing. For example, one ries the units B and C and is adjustably conunit may be used to project a light beam in a nected to the inner frame l2 by the screws l3, horizontal plane, while another unit may be held I and I5. As shown, the outer frame II has in a tilted position relative to the first mentioned spaced openings l6 and 11, respectively, for reunit to cause the light beam projected from the ceiving the units B and C and is provided at the 15 second unit to be inclined relative to the beam edges of said openings with rearwardly projectfrom the first unit. Therefore, it is an object of ing dished annular flanges l8 and I9, respecthe present invention to provide the units in the tively. that em ra e and form seats for the beads lamp casing with a mounting that will permit 1 of the units. are rubber gaskets between 20 said units to be readily adjusted whereby the Said heads 1 d flanges, nd 2| are split wire 20 beams of light projected from the units may be rings engag Suitable grooves in the flanges properly dire ted, and retaining the gaskets and units in assembled Other objects, advantages and novel details of relation!

What we claim as our invention is:

1. A lamp having a casing provided with an opening, a pair of laterally spaced light units in said casing for projecting light rays through said opening, and a common mounting for said units including a pair of cooperating frames, one being flxed in the opening in said casing, the second of said frames being substantiallyv parallel to the first mentioned frame and having dished annular flanges embracing and forming seats for said units, one of said dished flanges being offset relative to the other to hold the unit carried thereby in a tilted position relative to the other unit, and an adjustable connection between the frames independent of the casing permitting the second frame and units carried thereby to be bodily moved relative to the first mentioned frame and casing, the construction and arrangement of said units and annular flanges being such as to preclude movement of said units relative to each other, while permitting movement in unison of both of said units as aforesaid.

2. A lamp having a casing provided with an opening, a pair of laterally spaced light units in said casing, and a common mounting for said pair of cooperating frames, one being mounted in the opening in said casing and having a lateral flange, the secondof said frames being spaced from the lateral flange of the first mentioned frame, said second mentioned frame having dished annular flanges embracing and forming seats for the respective units, one of said dished flanges being oifset relative to the other so as to hold the unit carried thereby in a tilted position relative to the other unit, and an permitting movement in unison of both of said units as aforesaid.

3. A lamp having a casing provided with an opening,'a pair of laterally spaced light units in said casing for projecting light rays through said opening, and a common mounting for said units including a pair of cooperating frames, one being fixed to said casing, the second of said frames being substantially parallel to the flrst mentioned frame and having dished flanges embracing and forming seats for said units, one of said dished flanges being ofl'set relative to the other to hold the unit carried thereby in a tilted position relative to the other unit, and an adjustable connection between said frames permitting the second frame and units carried thereby to be bodily moved relative to the first mentioned frame and casing, the construction and arrangement of said units and dished flanges being such as to preclude movement of said units relative to each other, while permitting movement in unison of both of said units as aforesaid.
